Works Perfekt. Thanks a lot. What did i do.
I extracted the ATI Kextfiles from 10.6.8 with Pacifist /S/L/E. Deleted ATY_init. Put ati5000injector.kext to /E/E.
In Terminal: pfix for repairing Permisions und writing new Mkext. Reboot. Perfekt!

i had a fully working 5450 with 10.6.7 after many tries. Now after update to 10.6.8 (with pacifist) i dont bring it up to fully working. i will try a pacifist install of graphics update 1.0, and with the injector.

I prefer a Retail Snowleopard install.
But if you wont install again- did you tried newest VoodooHDA?
Nice Site for Diverss (kexts)

Should have this Audio Chip: Realtek ALC888 codec
At first you should know, which Audio CHip you have.
You can try this

Now i found this - from noob to noobs

D. Audio
The GA EP43 DS3L like many other motherboards uses Realtek ALC888 on board sound, this particular chip has been a nightmare for many users who have been unable to get sound on their hackintosh machines. The problem seems to be compounded by the fact that this motherboard is also contains the ICH10 intel south bridge making most ALC888 kexts uselss (as far as this noob can tell). A google search reveals an awful lot of people with problems and very few solutions.
I spent hours reading through large threads searching for a solution myself, and I confess that when I found it I'm not sure exactly how or why it worked, nevertheless here is a solution that should provide at least 2.1 audio output and mic input from the jacks at the back of the mobo.
(1) Download Kext Helper: http://cheetha.net/
And the 1.6.2a37 Kexts found at this link: http://www.mediafire.com/download.php?mndcdymtguy
Edit: This link is dead for some reason. Here is my own: http://www.mediafire.com/download.php?dn2vnuz5qhi
Or You can try the 1.5.7a24 ones here: http://www.mediafire.com/download.php?midnjn2to5u instead

Maybe a permission Problem. Did you enter your EDID?
YOu should have installed "pfix" from sojugarden.
http://osx86.sojugarden.com/2010/06/pfix-v3-1-released/
The Snowleopard Cache is more Tricky.
Delete all Graphics-kext files, Copy the files from 10.6.3 kextpackage, change the EDID, start pfix from terminal as root, reboot and hope.
Kextpackage for 10.6.3 in my Signature.

I think, you need a new Snowleopard installation.
But, dont delete your old drive with Leopard. It can be useful, if you get a problem with an update or anything else.
At first i would try a Retail EmpireEFI Installation with original Snowleopard disk.
But Snowleopard is a little bit more susceptible to booterrors , i mean.
You cannot boot with -F to solve any errors.
But i think you should try it with a new disk.
greetings and good luck

Try to buy an original Snowleopard, and Install it with EMPIRE EFI Boot CD, and after this install MyHack Installer.
I think you Disk are corrupt, or you burn to fast.
Did you tried Ideneb?
Please write your Signature! What kind of graphiccard is inside the Inspiron?

What kind of DVD Drive ? SATA or IDE?
Harddisk ? SATA or IDE?
Did you changed your BIOS Setting of Disk Controller to AHCI?
When does the KP come at boot? How do you boot ? with -x -v? With -v?
Would you like to try Snowleopard?
